Nkibintu bikomeye bya liw nibikoresho bya shimi, lignite yakwegereye amaso yimbere mu gihugu no mumahanga mugihe cyimyaka yashize kubera imiti yihariye hamwe ninganda zikoreshwa. Iyi ngingo izasesengura ibiranga Ligrite hamwe nagaciro kagereranijwe mu mbaraga, imiti nizindi murima bivuye kubitekerezo byimiti.
Literite nigicuruzwa gikomeye cyabonetse na hasi - ubushyuhe bwumye yamakara (impamyabumenyi igera kuri 600 - dogere 900. Ibigize imiti bifitanye isano rya hafi nubutaka bwibanze kandi bwumye. Ibice by'ingenzi byo guhirika karubone, ikibazo gihindagurika, ivu n'ubushuhe, muri byo biranga karubone bihamye ugereranije, ubusanzwe hagati ya 70%, hejuru cyane kuruta amakara asanzwe. Ibirimo byinshi bya karubone biha agaciro agaciro ka kanseri yo hejuru, muri rusange hagati ya 5500-7000 kcal / kg, bikabishyiraho lisansi nziza ya lisansi.
Ibirimo bihindagurika nikindi kintu gikomeye cyo guhirika, mubisanzwe hagati ya 8% {- 15%, munsi cyane kuruta amakara asanzwe (20% -40%). Iyi mikorere ituma ibiti bifite ibyuka bike byumwotsi mugihe yaka kandi urugwiro. Byongeye kandi, ibikubiye ivu biratandukanye bitewe nibikoresho fatizo nimikorere, muri rusange 6% -12%, kandi ivu rya Ac, hamwe nibyinshi mubyifuzo byiza birashobora kugenzurwa munsi ya 8%. Ibirimo bigufi bifasha kunoza imikorere yacyo muri metallurgie, inganda zimiti nizindi nzego.
Birakwiye ko tumenya ko ibintu bishimishije byo guswera bisanzwe, mubisanzwe hagati ya 0.3% {{2} {2}- 0.8% kuruta amakara menshi ya sulfur. Iyi mikorere ituma lisansi nziza yo gutunganya inganda nko gutwika itanura no gutesha agaciro, kandi birashobora kugabanya neza imyuka ya sulfuru. Muri icyo gihe, gukingura abakire muri hydrogen (hafi 4% -6%) hamwe nibintu bitandukanye bikurikirana, bitanga ibintu byingenzi byingenzi byinganda zamakara.
Ku rwego rwo gusaba, gukinisha byakomeje kwiyongera mu misaruro ya Calcium, Ferroalloy, hamwe na Pulfulle isukuye mu ivu ryayo rito, sufuruke yo hasi, hamwe n'agaciro gakomeye. Hamwe no gukomera politiki yo kurengera ibidukikije, hejuru -}}}} retel yanduye isimburwa no guhindaho buhoro buhoro, kandi isoko mpuzamahanga ryiyongereye cyane kuri yo.
Ibigize imiti byo guhindaho bizana ibyiza byo kurengera ibidukikije no gukora neza, kandi bigira uruhare runini mu guhindura ingufu n'iterambere ry'ibisifuro.
